Washing sure didn't help mine - first just rinsed in water - in the machine, then used OcyClean, vinegar - dabbing with a white rag, Clorox's version of Spray and Wash for colors, then washed in washer with Arm and Hammer detergent with OxyClean. It's better - but still there. Worst part is in the thread - off white thread is now BLUE! Will NOT use this product again!
